Volvo XC90: Driver support / Collision risk warning from driver support
The driver support systems Adaptive Cruise Control* and Pilot Assist* can
help alert the driver if the distance to the vehicle ahead suddenly decreases to
an unsafe distance.

Camera/radar sensor distance monitoring
Adaptive Cruise Control and Pilot Assist use approx. 40% of the braking capacity.
If a situation requires more braking force than driver support can provide, and
if the driver does not apply the brakes, a warning light and audible warning signal
will be activated to alert the driver that immediate action is required.
WARNING
The driver support system only issues a warning for vehicles detected by
its radar unit – thus, a warning may come after a delay or not at all. Never wait
for a warning. Apply the brakes when necessary.

Collision warning symbol on the windshield
In vehicles equipped with a head-up display*, a flashing warning symbol will
be displayed on the windshield.
NOTE
Visual warnings on the windshield may be difficult to notice in cases of
strong sunlight, reflections, extreme light contrasts, or if the driver is wearing
sunglasses or is not looking straight ahead.
* Option/accessory.
Passing assistance can be used with Adaptive Cruise Control* or Pilot Assist*.
Several conditions must be met for passing assistance to be possible.
In order to activate passing assistance:
your vehicle must be following a vehicle ahead (target vehicle)
your vehicle's current speed must be at least 70 km/h (43 mph)
the set speed must be high enough to safely pass another vehicle...
At certain speeds, vehicles with automatic transmissions and the driver support
functions Adaptive Cruise Control* and Pilot Assist* can switch target vehicles...
Other information:

filler door. The remote key must be in the vehicle in order to start the engine.

detected slippery road conditions is not always communicated between all vehicles
in the affected area.
This may be the case if:
No or insufficient Internet connection.
The maneuvers (steering wheel movements, acceleration or braking) made by
the vehicles on slippery surfaces are too weak for friction between the t..
